A few years ago there was a mass shooting in Japan. The government was calling for tighter gun control. Their gun control laws were so strict that the only kind of gun they could think of that hadn't already been banned was the nail gun. So, they banned nail guns. All the carpenters in the country were furious. They were saying things like, “If I wanted to kill someone, I’d do it with a regular hammer. I wouldn’t do it with a nail gun.”
